中文摘要

為了滿足IMT-Advance的技術規範, 在3GPP LTE-Advace與IEEE 802.16m的射頻技術中, 不約而同地使用了載道結合(Carrier Aggregation), 載道結合使用了數個較為窄頻之載道(Carrier), 各載道之資料會在媒介存取控制層(MAC Layer)結合,達成高速度資料傳輸的目的。這些載道可以是彼此相鄰的, 也可以是不相鄰的, 甚至是在不同的頻帶(Frequency Bands)中, 本文中描述了路由式收發機架構,在射頻路徑(RF Path)中,使用了路由式(Router)的結構,使得每一路的射頻路徑可以根據所需、而被指派不同數目之載道,如此一來,每一個頻帶就可以動態的分配到不同的硬體資源,以達成減輕硬體複雜度的目的, 所提出的架構使用Agilent ADS模擬並且更進一步使用儀器擬真驗證

英文摘要

To meet the IMT-Advance technical requirement, both 3GPP LTE-Advanced and IEEE 802.16m include carrier aggregation as one of the key RF
technologies. Carrier aggregation uses several carriers with narrow
bandwidth which will be combined in the upper layer for high data rate transmission. These carriers can be either adjacent to each other or in different bands. This work describes a transceiver architecture which
adopts router structure in the RF path. In the proposed architecture, each RF path can be assigned with different number of carriers according to the corresponding requirements for each band to reduce hardware
overhead. The proposed architecture is simulated with Agilent ADS and emulated with hardware for further validation.
